In 2013, Radiolab explored the concept of time. Paleontologist Neil Shubin discovered ancient coral fossils revealing shorter years millions of years ago. Astrophysicist Chris Impey attributed this change to Earth's slowing rotation due to its gravitational interaction with the moon. Robert proposed theoretical time-altering scenarios with astrophysicist Neil deGrasse Tyson. Radiolab has launched a contest to name a quasi-moon orbiting Earth. The show is supported by listeners and organizations like the Gordon and Betty Moore Foundation. Radiolab encourages audience interaction through social media and email. Leadership support for science programming comes from the Gordon and Betty Moore Foundation, Science Sandbox, and the John Templeton Foundation, with foundational support from the Alfred P. Sloan Foundation.
